ADJUSTABLE CONNECTING DEVICE FOR DRESS-FORMS.

Specification of Letters Patent.

Application filed November 26, 1913. Serial No. 803,121.

To all whom it may concern: I

Be it known that we, MIGHAEL LnnRY, Ti-ioMAs S. LEVIS, and BEN NELsON, citi Zens of the United States of America, residing in Chicago, county ofCook, and State of Illinois, have invented certain new and useful Improvements in Adjustable Connecting Devices for Dress-Forms, of which the following is a specification.

Our invention relates to frictional or yielding clamping and connecting devices,' particularly useful for adjustably connecting the sections of dress forms, an object of our invention being to provide an improved device of the above character which is simple, positive in its function as a yielding clamp, and also capable of being locked against adjustment.

In providing devices of the above character for use on sectional adjustable dress forms, it is desirable to have a device which will allow ready adjustment of the form without having to reach inside to vary the clamp. and at the same time hold the form securely in adjustment. It is also desirable to have a device which can be locked to prevent adjustment of the form. and to these ends we have provided an improved mechanism comprising preferably a corrugated or roughened connecting strip adapted to be held by pronged members yieldingly clamped to opposite sides of the strip so as to permit its adjustment, but which members may be firmly held against the strip to prevent adjustment thereof.

For a better understanding of our invention reference is to be had to the accompanying drawings in which like parts in the different views are indicated by like reference characters and in which:

Figure 1 is an interior view of the. front half of a dress form embodying our invention;

Fig. 2 is a View of our improved device when in its yielding position;

Fig. 8 is an end view of Fig. 2;

. Fig. 4 is a sectional view along line i, 4 of Fig. 2;

Fig. 5 is an edge view of Fig. 2;

Fig. 6 is a longitudinal sectional view along line 6, 6 of Fig. 2 but with the clamping nut adjusted so as to lockthe device and prevent movement thereo f;

Fig. 7 is a modified form of the body or fixed member; and

Fig. 8 is another modified form same member.

Referring now more particularly to the preferred construction of our invention, it comprises a connecting strip 1 preferably corrugated along its adjustable portion 1 and having a slot 1 through which the clamping screw 2 extends. When using the device as a single clamp it is preferably fastened by means of holes 1 but my invention is capable of use in various forms such as shown at A, B C, and D of Fig. Lthe form A being that illustrated in detail in Figs. 2 to (l. Prong-shaped members 3. 4:, are proof the vided at opposite sides of strip 1, the prong or projecting portions facing each other so as to ride upon the two faces of the strip when it is moved. Member 4 also has guides 4 which are adapted to prevent side or pivotal movement of the strip relative to its holding means. The fixed or body member may be secured to the form 5 in various ways such as by means of the screw 2 which extends through member 4 and carries a nut 6 for clamping the piece 4 to the body, rivets 10 also being used to prevent rotation of member 4 where desired. Screw 2 also extends through the strip 1 and clamping piece 3. there being a yielding element preferably in the form of a spring 7 positioned between melnbr 3 and a thumb nut 8.

'offorms,

longitudinal adjustment, the nut 8 is adthe projections of members 3, 4' rigidly grip the corrugated surfaces of the strip so as to In Fig. l, we have illustrated the interior of the front half of a dress form, showing one method of applying our invention to adjustable strips for connecting the different sections. The devices A-are as shown in Figs. 2 to 6, and the device B is a double connecting stri having yielding clamps at its two ends. 'lhe clamps C are T-shaped having a holding device at each of its three ends and D. is a double ended strip secured at its center. i

In connection with shoulder portions E, F

it is often desirable that they have both horizontal and vertical adjustment and to. this end we provide a T-shaped connecting strip 0 provided at its three end portions witha clamp similar to that of Figs. 2 to 6. It will be apparent that with this arrangement of a T connecting strip, the shoulder portions E, F, may be adjusted in either horizontal or 'vertical directions. In Fig. 7, we have shown another form of. the. fixed member 4 in which the guiding portions 4 are bent back and out so as-to provide fastening ears 4 so that the screw 2 need not pass through the form as in Fi 6. 'In Fig. 8 the guides 4: have ears 4 struc out therefrom.

Althoughin illustrating our invention we have con ned it to several forms, it will be apparent that other modifications will readily suggest themselves and therefore we do not desire to be limited to the exact structures as shown and'described but aim to cover all that which comes within the spirit Having described our invention what we claim as new and desire to secure by United States Letters Patent is:

1. An adjustable connecting device for dress forms comprising a corrugated sheet metal connecting strip, a body member supporting a pair of engaging elements adapted to ride upon the surface of said corrugations on oneside of the strip, a second pair of engaging elements adapted to ride upon the surface of the corrugations on the other side of said sti'ip, means for fastening said strip and body members to the form parts to be connected,,and means for yieldingly holding said engaging elements to permitlongitudinal adjustment of said strip.

2. An adjustable connecting device for dress forms comprising a sheet metal corrugated connecting strip, a body member supporting a pair of en aging elements adapted to ride uponthe su ace of said corrugations on one side of said strip, a second pair of engaging'elements adapted to rideu on the surface .of the corrugations on tlieot er side of said strip, means for fastening said strip and body members to the form parts to be connected, and means for yieldingly holding said-engaging elements to permit longitudinal adjustment of said strip, the last said means being adjustable whereby said engaging elements maybe-locked to prevent adji stment of thestrip.

3. An adjustable connecting device for dress forms comprising a sheet metal corrugated connecting strip, -a fixed device com-.

prising engaging elements adapted to ride upon the opposite surfaces of said corrugations, a lock-nut, and resilient means be-- tween said nut and certain of said engaging elements whereby said nut may be adjusted so as to permit adjusting inovement of the strip under opposing action of said elements or to lock said elements to prevent adjusting movement of said strip.

4. An' adjustable connecting device for dress forms comprising an elongated con-' clamping elements and the strip slot, a locknut threaded upon said clamping screw, and

resilientmeans positioned between the nut and the pronged clamping elements ,whereby said nut may-be adjusted for varying the clamping tension acting upon said clampingelements.
